ISHPEMING — Join the Ishpeming Rock and Mineral Club as it celebrates a half century of “Rockin’ and Swapping” at the 50th Annual Upper Peninsula Gem and Mineral Show. The event takes place from 9 a.m. to. 3:30 p.m. Saturday Aug. 1, at the Ishpeming Elks Club.

From humble beginnings as a small rock swap at Tourist Park in Marquette to the largest one-day rock show in the Midwest, this free event has grown and flourished. All are invited to this free, family-friendly event. Up to 50 vendors from the Great Lakes region will have gem and mineral specimens, jewelry and other gifts for sale. A children’s area features a scavenger hunt, treasure dig and other activities. Door prizes and a silent auction fill out the event.
